Abstract: The present invention is directed to a multiple propeller nozzle Venturi system and assembly consisting of two or more hydrodynamically shaped nozzle rings, axially located around the propeller and connected by the means of a plurality of equally spaced ring connecting fin struts to be used on a wide variety of sizes of watercrafts. By adjusting the conical inclination of one or more of the hydronamically shaped nozzle rings the water passing over is directed into the area of the propeller increasing the thrust pressure, thereby creating a Venturi effect. A skeg shield and a skid plate are incorporated to strengthen, or repair if broken, the lower portion of outboard and inboard-outboard motors. The overall effect of the multiple nozzle Venturi system is to enhance the performance, handling and control of a watercraft so equipped. Multiple nozzle Venturi systems are constructed to be adaptable to all sizes of vessels and all motors found on watercraft.

Abstract: A hanger for womens purses, handbags, shopping bags, or other articles, is provided which consists of a pair of elongated hinged support arms with a rubber semi-cylindrical bail mounted at the distal end of one of the arms, and with some means at the distal end of the other arm from which a purse, or other article may be suspended. The hanger is constructed to extend over the edge of a flat or curved surface, such as a table, chair arm, or the like, with the rubber bail engaging the surface in a non-slip relationship and with the article being suspended by the hanger over the edge of the table top, arm, or the like. The hanger is foldable to a compact configuration when not in use, and when so folded, it is constructed so that it may be used as a police whistle to summon help in cases of emergency.

Abstract: A power plant of the windmill type is provided which includes a multi-arm horizontal propellor unit mounted for rotation about a vertical axis. Each propellor vane of the unit includes an external shell configured to form an elongated trough with an open trailing edge. A webbing is mounted within the shell to form a series of cells which are exposed through the open trailing edge. The shell has a parabolic cross section, and its leading edge has an airfoil shape. The propellor unit responds to wind from any direction so that the need for wind tracking mechanisms is obviated. Moreover, the construction is such that gyroscopic vibrations due to wind changes are also minimized.
